What Is a Heat Pump Hot Water System?
Heat pump hot water systems are handy units that absorb warmth from the surrounding air and transfer it into hot water. They are often referred to as air-source heat pumps because of this. Heat pump hot water systems operate on electricity.
However, they are roughly three times more efficient than your usual electric water heater. When they are used in their ideal environment, they successfully save energy, reduce greenhouse gas emissions, and save money.
How Heat Pump Hot Water Systems Work
To extract the heat from the surrounding air, heat pump hot water systems use a unique refrigeration cycle. An insulated storage cylinder is then used alongside a heat exchanger to effectively heat the water. While these systems have been compared to reverse-cycle air conditions, they differ quite a lot.
Instead of running on a heat cycle, they heat water instead of the air in your home. Heat pump hot water systems don’t have a gas or electric boosting system, unlike solar hot water systems. They also use around 60% to 75% less electricity than your usual hot water system.
his is mainly due to the fact that the electricity used to operate the pump doesn’t heat with a direct element. Usually, heat pump hot water systems are installed outside the house on the ground. In some unique circumstances, they can be installed indoors.
This poses an advantage compared to solar water heaters. This is because collector panels do not need to be installed on the roof which makes installation far easier. Keep in mind, your heat pump hot water system must be installed in a well-ventilated area with access to a stream of air when operating.
